Brown researchers make major signal transduction discovery
Date:10/4/2007

ctivate this protein complex, Chin found, acetylation is required. Once that occurs, the complex travels to the cell nucleus to switch on anti-viral or tumor-suppressing genes.

The discovery of the acetylation of cytokine receptors marks a milestone in the study of signal transduction, the process of how cells receive and respond to chemical messages.

Many diseases, such as diabetes, cancer and heart disease, occur when signal transduction goes awry. That is why some drugs either inhibit or amplify signaling inside cells by targeting tyrosine phosphorylation. By showing that another chemical process is critical to signal transduction, Chins findings may explain why some anti-cancer or anti-viral drugs do not work for everyone. The findings provide an important new target for therapies that fight cancer and viral infectious diseases.
